Eco-sustainable construction

ADVANCED TECHNOLOGIES FOR ENERGY EFFICIENCY

Eco-sustainable construction was born in Germany in the late seventies, when, as a result of the energy crisis of '73 and in the wake of infant ecological movements, buildings began to move towards the use of techniques and materials that optimize energy savings, and do not pollute or harm the environment and people's health.

There are several directions of development of this new constructive approach: from research that take the building as a physical system whose behavior depends on the interaction between structural characteristics and atmospheric phenomena, to theories that attempt to reconcile environmental sustainability and aesthetics.

About 20% of the energy used to condition the interior of a home is lost through the walls, windows, roof and shell. The insulation of these structural elements, such as the insulation of external walls of a building, can reduce the energy requirements of the building up to 40%.

Today, the obligation to the insulation and energy efficiency is set by the regulations governing the construction of new buildings.

Since 2005, the 192nd Decree also requires energy certification in Italy: the buildings are classified into one of eight classes of consumption (from A + to G) according to the energy efficiency.

The subsequent 112th Decree of 2008 has made the energy certificate required for contracts for the sale or lease of a property.
